Goldmeadow Stalwart

White aggro has never simply been handed two power for a single mana; the design taxes it sideways instead of through the casting cost. You reveal a Kithkin card from your hand, proving you are committed to the tribe, or you pay the full the body would otherwise demand. That conditional is the entire engine. Stuff a deck with Kithkin and the reveal is nearly automatic, dropping a clean two-power beater on turn one; in any other shell it becomes a four-mana vanilla creature, which is to say unplayable. This is tribal-as-deckbuilding-constraint rather than tribal-as-bonus: the reward is not an anthem or a draw trigger but access to the aggressive rate at all, gated behind a density requirement the deck has to satisfy elsewhere. The reveal carries information, a small tell that you are holding more of the tribe, but because the cost is paid by showing a card rather than spending one, it never thins the hand it proves. The result is a one-drop that polices its own homogeneity: a creature type made a precondition for power instead of a flavor of it.
